Letters Patent No. 113,537, dated'April 1l, 1871.

VIMPROVEMNT IN WINDOW-SCREENS.

' The Schedule rean-ed to in these Letters Patent and making part of thesame.

To all whom 'it may concern Be it known that I, CHARLES F. LINSCOTlgVofChicago, in the county of Cook and State of Illinois, have invented anew and useful Adjustable Window-Screen; and l do hereby declare thefollowing to be a full, clear, and exact description thereof, which willenable others skilled in the art to which my invention apper tains tomake and use' the same, reference being had to the accompanying drawingforming a part'of this specification. A

Figure l is a plan view ot'fr'ny improved windowscreen extended to itsfullest capacity, and partly broken away to show the construction.

Figure 2 isa longitudinal section ofthe same in the line x :11, fig. l.

Figure 3 is a plan viewl of one of the adjustable slides applied to asection of thel main frame..

Similar letters of reference indicate corresponding parts in the severalfigures of the drawing.

My invention has for its object-to proyide a window-screen which can beadjusted laterally for .adaptation to windows of diiierent sizes; and,to this end,

It consists, primarily, in the arrangement, with the main screen, ofsupplemental frames and screens, of peculiar construction, adapted foradjustment to accommodate windows of differentl sizes upon oppositesides of the main frame, as will be hereinafter more fully described.

In the accompanying drawing- A is a quadrangular or othersuitably-formed frame, composed of wood or other proper material, andcovered with a wire or netting screen7 B. v

Upon opposite sides or edges ot'. the main frame supplemental frames areformed by means Voi' the rails O, secured to the main frame between theouter ends of metallic slides I).

These slides are each struck up' with side flanges,

lwhich iit over the top and bottom rails ot' the main '-frarne, and witha central tongue, E, adapted to vit and slide within grooves formed inthe edges of said rails.

The spaces between the rails C and main frarne are filled withwire-gauze or mosquito-netting, as found desirable. v

In fig. 1, the screen 'F is composed of wire, and in order to adapt thesame for folding up, it is creased or bentvto form folds similar to thefolds of a fan, as

shown at G, iig. 2, to admit of its being closed within a small compasswhen the rail G is movedtoward the main frame, :is shown in dottedlines, iig. l.

Ihe screen H, also shown in iig. l, is formed of netting, one edge beingsecured to the side ci' the main frame and the oppositaedge to a roller,l, placed within a circular recess in the inner edge of the rail C, andhaving its bearings in the metal slides.

When this rail is moved, toward the main frame to the position shown bydotted lines the netting is rolled upon the roller by any suitable meansapplied to thev journals of the latter.

In this example vof my invention I have shown screws 'J in the journalsof the roller, projecting through the vmetal slides, which, beingoperated by a screw-driver, turn the roller to Wind up the netting. Thenetting is, of course, unwonnd by the act of extending the supplementalframe..

'lhesupplevmental frames are locked in a closed or extended position bymeans of the adjusting-screws Kin the Ymain frame, passing throughlongitudinal slots L in the slides, as shown in iig. 3.

The anges upon the slides EV extend over the upper and lower ends of thescreens inthe supplemental frame, toprotect the same and to exclude dirtor insects.

If desired, the slides may be formed without the anges and tongue; but Iprefer this construction, as' it serves to render their operation moreuniform and exactl p By my invention I am enabled to supplywindowscreens to the trade which can'be adjusted to any sized windowwith the utmost accuracy and despatch.

I design to manufacture them injthree sizes, to include the smallwindows oivdwelling-houses and the larger windows of stores, &c.

A special advantage derived from the construction of my improved screenis that the main frame, occu- `pying comparatively a large space in thecenter'of the screen, the view through the netting or gauze is unobstructed by the rails or other parts of the supplemental frames.v l iI do not claim, broadly, an adjustable windowscreen, as I am aware thesame isnot new.

' yHaving thus described my invention,

W'hat I claim as new, and desire to secure by Letters Patent, is

1'. rIhe supplemental frames and screens, arranged for adjustment uponopposite sides of the main frame,l substantially as shown and described,for `the purpose specified. Y 2. The combination of the `foldingwire-screen F, with the supplemental frame and the main frame A,substantially as described, for the purpose specified.

3. 'Ihe combination ol" the roller I with the supplemental frame,rthenetting-screen H, and the main frame A, substantially as described, forthe purpose specified.

4. The adjustable slides D, constructed substantially as described, incombination with the rails C and the main frame A arranged as shown, forthe purpose specified.
